Protection and automatic recovery circuit system

Abstract

The circuit system contains an output control circuit, an output stage circuit, a current sensing circuit, and a delay circuit. The output stage circuit is driven by the output control circuit and monitored by the current sensing circuit. When the current sensing circuit determines that there is a short circuit or an abnormal current in the output stage circuit, the current sensing circuit delivers an output signal to disable the output control circuit, which in turn stops the output stage circuit. The output signal is also sent to the delay circuit which, after a period of time, provides a trigger signal to reset the current sensing circuit and to enable the output control circuit again. By providing a large enough delay time, the output stage circuit is able to sustain a very large peak current to prevent it from being damaged.
